PowerPath: Połączenie resetowane przez peera podczas skanowania portu 9083 przez lukę umożliwiającą utrzymanie

Summary: PowerPath dla systemu Windows 7.2.X Zdalne zarządzanie z zabezpieczeniami Mutual Transport Layer Security (mTLS) osiąga maksymalny limit połączeń gniazd i połączenie resetowane przez peera, gdy możliwa do utrzymania luka skanuje port 9083. ...

Symptoms

Gdy oprogramowanie skanujące Tenable skanuje port 9083, proces zdalnego zarządzania PowerPath z włączoną obsługą protokołu mTLS kończy się niepowodzeniem, ostatecznie osiągając maksymalną liczbę połączeń gniazda i rejestrowany jest komunikat resetowania połączenia przez element równorzędny.

 

W graficznym interfejsie użytkownika PPMA stan rozłączenia jest widoczny dopiero w następnym cyklu odpytywania. Po uruchomieniu cyklu sondowania serwer ostatecznie pokazuje się w graficznym interfejsie użytkownika jako odłączony (CZERWONY).

Cause

Jest to problem z funkcją zdalnego zarządzania PowerPath dla systemu Windows 7.2.X z włączonym protokołem mTLS, który nie obsługuje poprawnie połączeń Winsock z serwera innego niż PPMA.

 

Resolution

Poprawka będzie dostępna w przyszłej wersji programu PowerPath dla systemu Windows, ale obecnie nie ma terminu dotarcia do celu.

 

Obejście problemu polega na ponownym uruchomieniu usługi "EMC PowerPath Remote Management Component" z poziomu usług systemu Windows.
